Yu Yi Swallow, who has a desire to be tied up, is tied up for the first time. Captive and confined, her body is deprived of freedom by ropes and restraints, and she writhes in fear. Gagged and unable to make a sound, she cries for help, moans, struggles, and suffers... She is in a desperate situation! She struggles desperately to escape the ropes, but the more she struggles, the more the ropes creak and tighten around her body. Restrained in a sprawling position, the heroine can only moan in despair, and a look of despair and pain appears on her face. Bonus: bondage SM training.
